Dennis Marchant has been remembered as a “man with a heart of gold” following his recent passing.
A celebration of a career in hard rock for a man with a heart of gold.
We honour the memory of Dennis Marchant, better known to us as Marcho—a colleague who was not just a co-worker but a true professional and an inspiration to all.
Marcho’s career in the resource industry began with humble beginnings, starting out in a sapphire mine in Inverell. It didn’t take long for him to find his passion for mining and learn the basics of open-cut operations. This foundation propelled Dennis to manage Mackay’s largest hard rock quarry, now known as the Heidelberg Farleigh Quarry, where he dedicated 36 years of his working life.
Though Dennis disliked school as a young boy, he made it a point to improve his education as an adult, ultimately earning his Diploma in Extractive Industries. He took great pride in overseeing the largest hard rock quarry in the Bowen Basin.
In 2021, Dennis received one of the highest honours from The Institute of Quarrying Australia—he was awarded Quarry Manager of the Year. Who would have imagined that the 15-year-old farm boy from Mt Russell would go on to manage the largest hard rock quarry in the Mackay district and positively impact the lives of many young people by mentoring them in heavy machinery operations and extractive industries? Dennis was highly respected and loved by his colleagues and the Mackay community for his integrity within the industry.

Dennis had no biases; he didn’t see colour, race, religion, or gender. When it came to quarrying, if you were willing to learn and show up to work, he was ready to teach you, regardless of who you were. He generously shared his knowledge and passion for the industry with anyone willing to listen.
During Dennis’s Celebration of Life, held in Mackay and attended by many colleagues, family, and friends, it was commonly expressed that without Marcho, they would have never gained their footing in the quarry industry.
His unwavering dedication to the Institute of Quarrying Australia forged the foundation for the inaugural Mackay events, inspiring a legacy that will endure for many years to come.
Dennis was exceptional, inspiring, and humble—not only in his career and professional achievements but also as a member of his community. Most importantly, he was a loving husband of 35 years to his wife, Kay, and an adored father to his daughter, Jess.
A man well ahead of his time, he was a true gentleman who rarely raised his voice and willingly mentored anyone eager to learn. Always prepared to lend a helping hand wherever he could, Dennis’s passion for the quarry industry was infectious, and his contributions are remarkable. He leaves behind a legacy that will continue to shape many careers and lives.
